SPECIFICATION forming part of Letters Iatent No. 698,159, dated April 22,1902.

Application filed March 19, 1901.: fierial No. 51,922- (No model.)

To all whmn it may concern.-

Be it known that I, ABRAHAM VANDER- BEEK, a citizen of the United States of America, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and. useful Improvement in Universal Joints, of which the fol lowing is a description, reference being had to the accompanying drawings, wherein Figure 1 is a perspective view of a universal joint embodying said improvement. Fig. 2 is a View of the same, partly in section and partly in elevation, with one shaft at right angles to the other. Fig. 3 is a sectional view on the planewmof Fig. 2 looking in direction indicated by the arrows. Fig. 4 is a detail view, in central section, of the block. Fig. 5 is a side view of the bifurcations of one shaft with its appurtenant trunnion shafts in position. Fig. 6 is a view similar to Fig. 3, showing a modification in which the trunnion-shafts are parts of spheres. Fig. 7 is a view similar to Fig. 3, showing a modification in which the trunnion-shafts are regularly cylindrical.

The object of the improvement is the production of what is known as a universal joint having features of novelty and advantage whereby one shaft drives another out of alinement with itself. The two shafts are bifurcated at the ends which are joined.

In the accompanying drawings the letter a denotes the bifurcations of one shaft, and b the bifurcations of the other shaft.

The letter 0 denotes what may be termed an intermediate block. Before the trunnion-sockets are cut in it it is preferably very near like a cube in shape; but the exterior shape is not essential, for it may be varied at pleasure.

The letters (1 and 6 denote four-trunnionshafts, which fit into trunnion-sockets which are cut for them in the intermediate block 0. The trunnion-shafts d are appurtenant to the bifurcations a. and the trunnion-shafts e are appurtenant to the bifurcations b. The trunnion-shafts may be attached to their respective bifurcations in any suitable manner, but preferably as by screws f and g.

The letter f denotes two screws appurtenant to the bifurcations a. Theyrun through the same. They are threaded into the trunnion-shafts d.

The letter g denotes two screws, which are appurtenant to the bifurcations I). They run through the same. They are threaded into the trunnion-shafts e, and they likewise bear on the central part of the block 0. By means of the screws f the trunnion-shafts d can be made to bear against the bifurcations a with any desired pressure, and in like manner by can be made to bear against the bifurcations b with any desired pressure.

There is a cross-like opening 0 in the central part of the block 0, which for one thing permits the circulation of the oil.

The letter i denotes two stop-pins, carried respectively by the trunnion-shafts d and e, fitting into cooperating and corresponding mortises in the bifurcations a and b, by means of which the trunnion-shafts d and e are prevented from rotation with reference to the bifurcations a, and b.

The letter h denotes an oiling-duct. It contains the spring is, on which rests the ballvalve k', which is kept from escaping from the oiling-duct by the collar Z, suitably fastenedrin the mouth of the oiling-duct. To oil the device one has but to push the ballvalve down a little with the tip of his oil-can and immediately on the removal of the oil-can the spring pushes the ball-valve back against the collar and closes the mouth of the oiling duct.

The trunnion-shafts of Figs. 1 to 5, inclusive, are conical, those of Fig. 6 are parts of spheres, and those of Fig. 7 are regularly cylindrical.

I claim as my improvement 1. In combination the two bifurcated shafts, the four trunnion-shafts removablybut nonrotatably secured thereto, and an intermediate block having four trunnion-shaft bearingsockets, all substantially as described andfor the purposes set forth.

2. In combination the two bifurcated shafts, a trunnion-shaft removably but non-rotatably secured to each fork, an intermediate block having sockets adapted to the shape of the means of the screws 9 the trunnion-shafts e trunnion-shafts, and also adapted to move back and forth thereon.

3. In combination the bifurcated shafts, a trunnion-shaft removably attached to each fork, interlocking parts on each trunnionshaft and the fork to which it is attached, and an intermediate block having sockets adapted to receive the trunnion-shafts, substantially as described.

4. In combination the two bifurcated shafts, a trunnion-shaft secured to each fork thereof by means of ascrew, projections on the trunnion-shafts adapted to enter recesses in the forks, an intermediate block having sockets adapted in shape to the shape of the trunnion-shafts and arranged to connect said shafts, substantially as described.

5. In combination the two bifurcated shafts, the trunnion-shafts in the form of truncated cones removably secured to the said forks, an intermediate block having conical sockets adapted to receive and work on said trunnion-shafts, the parts being so arranged that the apices of the conical trunnion-shafts meet at substantially the center of the intermediate block, substantially as described.
